Activation Reactions of Cp, ZrCl, and Cp, ZrMe, with Aluminium Alkyl Type Cocatalysts Studied by , Fated by . FTIR spectroscopy. The studies have been performed in a cell that allows continuous monitoring of the reactions and stepwise additions of reactants. Most bands of the zirconocenes are unaffected by the reactions, but a strong Cp band at 803-822 cm. was found to give distinct information on

Single Component Zirconocene Catalysts for the Stereospecific Polymerization of MMAghly isotactic poly(methyl methacrylate) (PMMA) with Me.C(Cp)(Ind)Zr(Me)(thf).BPh.. 1 as a catalyst, and syndiotactic PMMA at low temperatures with Me.C(Cp).Zr(Me)(thf).BPh.. 2. Similar cationic complexes with other ligands have been found to be inactive for MMA polymerization under similar reaction

Phosphinoalkyl-Substituted Cyclopentadienyl Chromium Catalysts for the Oligomerization of Ethyleneess attention and have never found commercial use. Reported here is a new family of phosphinoalkyl-substituted cyclopentadienyl chromium compounds which, after activation with methylalumoxane, give highly active homogeneous catalysts for the oligomerization and polymerization of ethylene whereby the

Rare Earth Half-Sandwich Catalysts for the Homo- and Copolymerization of Ethylene and Styreneesis of the alkyl complexes [Ln(η.:η.- C.Me.SiMe.NCMe.)(CH.SiMe.)(THF)], easily accessible by the reaction of the amino-cyclopentadiene with [Ln(CH.SiMe.).(THF).], was developed. The dimeric lanthanide hydrido complexes are highly fluxional involving THF dissociation and cis-trans isomerization of t

The New Revolutionary Development Of Catalysis As The Driving Force For The Commercial Dynamic Succest families in the fifties activated a process that entered in a dynamic revolutionary development, still very much in progress in the present days, after having been kept quiet and at a very low profile for two decades. Their early development, in spite of the bright promises, was more difficult th
